Abstract
A flexible duct for handling conditioned air comprises an inner core, a vapor barrier, and a compressible core spacer positioned between the inner core and vapor barrier. The compressible core spacer is made of a film material with a helical support integrated therewith. The compressible core spacer is made of a length longer that the inner core and other duct components so that when the compressible core spacer is compressed when assembling the inner core and vapor barrier, the film material between adjacent sections of the helical support folds to create a spacer-liker construction that creates air gaps between an outer surface of the inner core and an inner surface of the compressible core spacer and outer surface of the inner core and vapor barrier. With a pair of low-e surfaces associated with the compressible core spacer or the compressible core spacer and inner core, reflective insulation systems are created to improve the insulating value of the insulated flexible duct.
